During an expedition to document Arctic wildlife, I observed a polar bear family from a small, ice-going vessel. The mother and her cubs were living on pack ice far from land. Incredibly intelligent animals, young polar bears learn quickly through their inquisitive nature. This cub was intrigued by its reflection and was studying it with great interest, photographer Florian Schulz said. Florian Schulz / NBP Awards sharonrhoover
A cheeky polar bear sticks out her tongue at Amsterdam Zoo. Photographer Lars van de Goor said: 'I was taking pictures of the animals and noticed this polar bear. I spent half an hour running from left to right, repositioning myself time and time again to get myself into the right position. Then she finally looked straight into my camera and stuck her tongue out.'
